When and where should I use var
, let
, and const
in JavaScript? I am aware that let
variables can be reassigned to a new value but const
variables cannot be reassigned to a new value. When I write JS code, I find myself using let
almost all the time just because it allows reassignments. Is there any case where using const
would be preferable? Also, is there any scenario where I should still be using var
?
